> Issue Type: New Feature
> Reporter: Xinli Shang
> Assignee: Gang Wu
> Priority: Major
>
> During the discussion of PARQUET-2071, we came up with the idea of a
> universal tool to translate the existing file to a different state while
> skipping some level steps like encoding/decoding, to gain speed. For example,
> only decompress pages and then compress directly. For PARQUET-2071, we only
> decrypt and then encrypt directly. This will be useful for the existing data
> to onboard Parquet features like column encryption, zstd etc.
> We already have tools like trans-compression, column pruning etc. We will
> consolidate all these tools with this universal tool.
